Stratasys Awarded 3D printing Seam Concealment Patent

[Gyrobot]

Somebody skilled in the art will know this practice, which should fail the patent process due to prior art. As an experienced CNC programmer, the technique of arcing on and off a profile is well known in the machining and laser cutting fields to eliminate dwells and artefacts on the item. 3D printing is no different.

For Laser cutting example :


For CNC machining example, leading in at B(1,4) :

Gyro, do you set in the software, or the piercing point and arc leads are done through the cad manually? Also, if I do in cad do I have to play with the vector order?

I am having trouble with my laser cutted disk, they have this transition area that are just annoying.
